VScode+Flutter 开发继续踩坑

运行慢解决方法1：修改build.gradle,注释掉jcenter()，google()。使用阿里的镜像。原因是jcenter google库无法访问到导致的问题。虽然我有万能的爬墙工具，开启全局代理依然被我们伟大的发改委墙掉了！
 
buildscript {
    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
    }
 
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}
 
allprojects {
    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
    }
}
 
 
第二步：找到fluttersdk目录 进入如下目录
 
Macintosh HD⁩ ▸ ⁨用户⁩ ▸ ⁨rabbit⁩ ▸ ⁨资源库⁩ ▸ ⁨Flutter⁩ ▸ ⁨packages⁩ ▸ ⁨flutter_tools⁩ ▸ ⁨gradle⁩
找到下 flutter.gradle文件 找如如下内容替换成和我一样的 把jcenter注释掉。
 
​buildscript {
    repositories {
        //jcenter()
        //maven {
        //    url 'https://dl.google.com/dl/android/maven2'
        //}
        maven{
            url 'https://maven.aliyun.com/repository/jcenter'
        }
        maven{
            url 'http://maven.aliyun.com/nexus/content/groups/public'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}
至此从新运行，解决掉问题。

上面问题解决：

  • 手动下载 gradle 并解压。
  • 找到项目/android/gradlew.bat打开。
  • 找到set CLASSPATH=%APP_HOME%\gradle\wrapper\gradle-wrapper.jar替换为set CLASSPATH=<path_to_downloaded_gardle>\gradle-4.6\lib\gradle-launcher-4.6.jar。
  • 找到"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %GRADLE_OPTS% "-Dorg.gradle.appname=%APP_BASE_NAME%" -classpath "%CLASSPATH%" org.gradle.wrapper.GradleWrapperMain %CMD_LINE_ARGS%替换为"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %GRADLE_OPTS% "-Dorg.gradle.appname=%APP_BASE_NAME%" -classpath "%CLASSPATH%" org.gradle.launcher.GradleMain %CMD_LINE_ARGS%。
  • 重新执行flutter run。
